TY - RPRT A1 - Imbierowicz, Björn A1 - Wahrenburg, Mark T1 - The impact of reasons for credit rating announcements in equity and CDS markets N2 - Over the last four decades the literature on bond rating changes and its effects on security prices increased significantly with almost all studies not controlling for the respective reason for those. We therefore investigate the impact of rating events on the stock and the credit default swap (CDS) market incorporating rating reviews and rating changes together with the reason mentioned by the rating agency. Our results for the general effects are in line with prior findings but conditioning on the respective reason shows that the markets’ anticipation of rating actions is largely driven by events due to changes in firms’ operating performance. Furthermore, we provide empirical evidence for the hypothesis in prior literature that a surprise downgrade does not necessarily have to be bad news for stockholders when wealth is transferred from bondholders, but negative rating actions are always bad news for bondholders. The results additionally reveal increasing rating announcement effects by declining credit quality of firms for both rating reviews and changes. JEL Classification: D82, G14, G20.
